SELF-ADJUSTING CARRIAGE-SEAT.

Specification of Letters Patent No. 31,023, dated January 1, 1861.

To all whom it may concern:

Be it known that I, JOHN C. KIMBALL, of the city and county of NewHaven, in the State of Connecticut, have invented a new and usefulImprovement in Self-Acting Adjustable Carriage-Seats; and I do herebydeclare that the following is a full, clear, and exact description ofthe construction, character, and operation of the same, reference beinghad to the accompanying drawings, which make part of this specification,in which Figure 1, is a perspective view of the main portion of the bodyof the carriage, showing it as used with one seat. Fig. 2, is aperspective view of the same, showing it as used with two seats. Fig;*3, is a longi tudinal section of the same, showing the connection ofthe legs, &c., and their position when two seats are used. Fig. 4, is alongitudinal section of the same, showing the position of the legs, &c.,when used with one seat. Fig. 5, a perspective view of a portion of theforward seat, showing (in dots,) its position when not used, (as in Fig.1.)

My improvement consists in so connecting the seats with the inner sidesof the body, and with each other, that by taking hold of the main, orback, seat, slightly raising it, and pushing it forward, the action ofthe legs, &c., will draw back and depress, the forward seat, and placethe main seat over it, without touching the edge of the body, (inpassing either way, to wear or injure it-,) so that it will appear as aone seat carriage,-and, of course, raising the seat and pushing itbackward, will raise the front seat and carry it forward, to itsposition for use,-and place the main seat in its proper position, sothat the whole will be ready for use, as a two seat carriage, (as inFig. 2).

I make the body, A, of the carriage, substantially, as represented inthe drawings or in any other suitable form.

I make the main seat, 13, substantially, as shown in Figs. 1 and 2, andindicated in section, in Figs. 3 and 4.

I make the forward seat, C, substantially, as represented in Fig. 2, or,in-any other suitable form.

I attach the main seat, B, to four legs, or bars, two at each end, asrepresented at a, and 72, Figs. 2, 3, and 4, which support the frontportion of the seat when it is used as a back seat, (for the two seatcarr1age,) as shown 1n Figs. 2 and 3, and on which the seat is carriedforward, to

the position shown in Figs. 1, and 4, (where it rests upon the edges ofthe body.)

I attach the forward seat to four legs, or bars, two at each end, asrepresented at 0, and (Z, Figs. 3, and 4, which legs sustain, orsupport, it when used, as in Fig. 2.

I connect the legs, or bars, of the seats by the bars, 6 and 9, Figs. 3,and 4, (the front seat being attached to, or made a part of the pieces,or block, it.)

Having made the several parts, and connected them as herein described,ifI wish to use the carriage with two seats, (as in Fig. 2,) I carry theseat, B, backward, on the legs, or bars, a, and b, (as shown in Figs. 2,and 3,) and steady it in its latter position by pins, or projections, asrepre sented at Z, Figs. 1, 2, 3, and'4, on the pump handles, m. But ifI wish to use the carriage with but one seat, (as represented in Fig.1,) I slightly raise the back seat, B, and carry it forward, when thebar, 6, by its connection with the slotted bar, g, and piece, it, willcarry the front seat, C, Fig. 2, backward, and downward, to the positionindicated in Fig. 4, and shown. in dots, in Fig. 5, and the main, orback, seat, B, will come down over it, all as represented in Fig. 1,(the ends, D, and D, of the front seat, being turned down flat, by theaction against the edges of the body, as shown in dots at D, in Fig. 5.)

The advantages of my improvement consist, (in part,) in the ease, andreadiness, with which I can change from a one, to a two, seatedcarriage, and vice versa, as it requires no preparation, but may bedone, at any time, by simply taking hold of the main seat, slightlyraising it, and pushing it forward, or backward, (as the case may be,)all which may be done in two seconds, of time, and with the power of onehand, if necessary ;and, in that, neither of the seats need to befastened in their places by any other means than the regular operationof the legs on which they are supported, and

be handled separately, and that sliding seatshave been made adjustable,so as to constitute a one, or a two, seat carriage, as patented byGeorge J. Lucas April 27, 1858, but, these seats move backward, andforward in a right line, and neither of the seats are moved on legs,which would give them a curvilinear motion when moved backward andforward, as they must then rise and fall on their legs, so as not totouch the railing of the box. I, therefore, do not claim any such, as myinvention, nor any other means, or device, which would be applicable to.sliding seats thus moving in a right line, but

What I claim as my invention, and desire to secure by Letters Patent,is-

So constructing, and connecting, the two seats that the curvilinearmotions of the back seat will perfectly control the curvilinear motionsof all parts of the forward seat, when the two, seats are constructed,connected, and made to produce the result, substantially, as hereindescribed.
